Variable Sub-Pixel Opening Area for Arc Display Zigzag Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing irregular-shaped display panels exhibit a zigzag pattern in arc areas due to the use of black matrix material to shade sub-pixels, affecting display performance and visual appearance.
Innovation Solution
A display panel design featuring a transition area with sub-pixel areas that have openings whose areas decrease gradually from the display area to the non-display area, eliminating the zigzag pattern and enhancing luminance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If black matrix material is used to shade sub-pixels outside the arc edges, then the screen-to-body ratio is improved, but a zigzag pattern appears in the arc areas affecting display effect
Solution Approach 1:
The patent applies different opening area configurations to different regions of the sub-pixels. Specifically, sub-pixels in the transition area have different opening area configurations compared to sub-pixels in the display area, creating local variations in light transmission properties to eliminate the zigzag pattern while maintaining high screen-to-body ratio
Solution Approach 2:
The patent changes the opening area parameter of sub-pixels based on their location. Sub-pixels closer to the arc edge have different opening areas compared to those farther away, creating a gradual transition in light transmission that eliminates the zigzag pattern while achieving high screen-to-body ratio
2Object-generated harmful factors
If sub-pixels are processed to ensure smooth display performance in arc areas, then display effect is improved, but the structure becomes more complex
Solution Approach 1:
The patent implements local quality by configuring different opening areas for sub-pixels in the transition area versus the display area. This localized differentiation ensures smooth display performance in arc areas without requiring complex processing across the entire display panel
Solution Approach 2:
The patent segments the display panel into distinct areas (display area and transition area) with different sub-pixel configurations. This segmentation allows for simplified processing within each zone while achieving overall smooth display performance across the arc regions

AI summary
The present application provides a display panel and a display module with variable sub-pixel opening area. The display panel includes a display area, a non-display area, and a transition area disposed between the display area and the non-display area. The transition area comprises a first sub-pixel area and a second sub-pixel area, and the first sub-pixel area comprises a first opening and the second sub-pixel area comprises a second opening. The first opening is disposed closer to the display area than the second opening, and the first opening has an area greater than the area of the second opening.
